American stealth bombers are expected to land at U.K. military bases within days to join the U.S.-Israel campaign against Iran, according to reports.

Citing unnamed senior Western officials, The Telegraph reported Wednesday that air bases at Diego Garcia in the Indian Ocean and RAF Fairford in Gloucestershire are being readied for the arrival of B-2 Spirit stealth bombers — the $2 billion strategic bomber is also known as the world's most expensive aircraft.

The bombers are understood to be landing at the U.K. bases "in a matter of days" as Washington intensifies operations in the region, the outlet reported.

As previously reported by Fox News Digital, the U.S. military used stealth B-2 bombers to strike Iranian ballistic missile facilities Feb. 28 as part of the launch of Operation Epic Fury.

U.S. Central Command (CENTCOM) confirmed that B-2 stealth bombers, which were equipped with 2,000-pound bombs, struck Iranian "hardened" ballistic missile sites.

The U.S. was cleared to use British bases for limited strikes on Iran’s missile capabilities on Feb. 29 after Prime Minister Keir Starmer signed off on the plan, and while U.K. Defense Secretary John Healey stated Britain had "stepped up alongside the Americans."

Starmer said the authorization was granted to protect U.K. and U.S. allies as the conflict escalated. He had previously said he would not allow American forces to use U.K. bases for offensive operations in the region.

Tensions have since been heightened in the U.K. by security incidents in Cyprus. RAF Akrotiri, a key British military base on the island, was struck by a suspected drone on March 2, causing minor damage.

The unmanned aircraft was reported to resemble an Iranian-made Shahed drone, similar to models used by Russia in Ukraine and by Tehran’s regional proxies.

The Ministry of Defense said force-protection measures were at the "highest level" and that the base had taken steps to defend personnel. About 4,000 service members and their families are based at RAF Akrotiri.

The U.S. State Department raised its travel advisory for Cyprus to Level 3, urging Americans to reconsider travel because of the threat of armed conflict and limited consular assistance in parts of the country.

Non-emergency embassy staff and family members were authorized to leave. Officials said the advisory change reflected adjustments in embassy operations rather than a direct change in underlying risk.

Trump had called Britain "uncooperative" and slammed Starmer as "not Winston Churchill" after Starmer initially rebuffed a U.S. request to use U.K. bases to attack Iran, according to The Associated Press.

Trump has also condemned Britain’s agreement to hand over the Chagos Islands, home to the Diego Garcia base, to Mauritius.
